Title: Driving device of ink jet head
Inventor: MUKOYAMA KEIICHI
IPC: B41J2/045
Filed: 1994-02-08
Abstract: PURPOSE:To obtain stable printing quality while making the emission amt. of each nozzle constant by providing a switching circuit changing over a switching element to a second phase after charged sufficiently for the contact of an electrode with a vibration plate to emit an ink droplet. CONSTITUTION:In contact driving wherein a vibration plate 5 is driven by charging sufficient to bring the vibration plate 5 and an electrode 21 to a contact state, the emission amt. per a time of ink is determined by the max. vol. change quantity dV of an emission chamber 6. That is, since the electrical and mechanical stress applied to the electrode 21 and the vibration plate 5 is large in the contact driving as compared with non-contact driving, a head becomes easy to destruct but, since voltage equal to or higher than the voltage (contact voltage) bringing the vibration plate 5 into contact with the electrode 21 is always applied, the emission amt. per a time of the ink emitted from each nozzle, that is, the max. vol. change quantity dV of the emission chamber is uniquely determined on the basis of gap length G and, therefore, if the gap length G and the thickness of the vibration plate are accurately set, the emission amt. of ink becomes stable and a high printing quantity is obtained.

Title: Method for displaying ultrasonic image
Inventor: DEIITORITSUHI HASURAA
IPC: A61B8/14
Filed: 1991-01-14
Abstract: PURPOSE: To compensate the disturbance of an image based on nonuniform ultrasonic velocity distribution even when the thickness of a disturbance layer is increased. CONSTITUTION: In a method for displaying the tomographic plane of an object as an ultrasonic image on the basis of the nonuniform speed distribution in the vicinity of a surface, the tomographic plane is scanned at every line in an adaptation stage by a converter array. The deviation value of signal delay is calculated from an echo signal wherein a scanning line is focused through the crosscorrelation function of an element converter adjacent as compared with an expected value at a time of equal speed distribution. A correction value is formed from the deviation value in relation to the incident angle (-B5-B5) of the echo signal on the element converter. A delay value for focusing is altered in an image display stage succeeding to an adaptation stage in relation to the incident angle (-B5-B5) of the echo signal and the correction value to this incident angle.  By this constitution, the stimulation of an image based on unequal speed distribution can be compensated even at a time of the disturbance layer in the vicinity of a thick converter.

Filed: 1991-01-14
Abstract: PURPOSE:To make the title material superior in mechanical strength and low in anisotropy even if a quantity of resin is a little, by constituting a molding base including a carbon film and resin. CONSTITUTION:Any of carbon films having, for example, polyacrylnitrile, phenolic resin, cellulose and pitch as starting material can be used as a carbon film. Among those carbon films, mesophase pitch carbon film having the high tensile modulus of elasticity, especially a pitch carbon film having a thickness of about 10-40mum, preferably an aspect ratio (width/thickness) of about 10-1000, 30-300 is preferable. Thermosetting resin or thermoplastic resin or their mixture can be used as resin. A ratio of the resin to the carbon film is ordinarily 1-50wt.%, preferably about 5-30wt.%. Since the carbon film has a narrow surface area as compared with that of a carbon fiber and can be integrated by joining on a plane surface pat, a quantity of the resin within a composite material can be reduced remarkably.

Title: Shift shock reducing device for automatic transmission
Inventor: ISHIKAWA KAZUO
IPC: F16H61/08
Filed: 1979-02-13
Abstract: PURPOSE: To prevent engagement shocks from occurring in a friction engagement unit in a motor vehicle both while the vehicle is running and when the vehicle is stopped, by connecting a shock control valve to an intensifying chamber of a regulator valve which is used for regulating an increase in an engagement liquid pressure in the friction engagement unit.  
     CONSTITUTION: A shock control valve 170 is connected to an intensifying chamber 181g of a regulator valve 180 which is used for regulating an increase in an engagement liquid pressure in a friction engagement unit. The shock control valve 170 is adapted to supply, only when a governor pressure is generated, a liquid pressure received from a valve which is operated in accordance with the degree of opening of a throttle. This structure conducting a checking operation with reference to a governor pressure as to whether the vehicle is running or whether the vehicle is stopped. Accordingly, an initial adjusting pressure of a modulator can be set to a higher level while the vehicle is running, and to a lower level when the vehicle is topped. As a result, the friction engagement unit is put in an engaged state comparatively speedily while the vehicle is running, and slowly when the vehicle is stopped. Thus, engagement shocks can be prevented from occurring in a friction engagement unit both while the vehicle is running and when the vehicle is stopped.

Abstract: PURPOSE:To speed up an etching rate and obtain a higher etch factor product by introducing a printed board on the surface on which a conductor is formed into an etching solution and turning said conductor into an anode and then charging between the anode and a cathode. CONSTITUTION:An electrolytic etching tank 11 is filled with an etching solution 5, into which a printed board 1 is introduced by driving a conveyor 2. DC current is applied to a cathode 13 made of a copper plate connected with a plasma electrode from a power supply device 14, thereby carrying out electrolytic etching. The copper clad formed on the surface of the printed board as a conductive layer is affected by the chemical action of the etching solution 5 so that copper may be dissolved out from the copper clad, promoting the dissolving of the copper. On the other hand, in the cathode 13, copper ions receive electrons so that the metal copper may be separated out. Therefore, it is satisfactory to replenish the same amount of etching solution which is used for the etching.
